Accredited Mass Management Scheme (AMMS)

This scheme allows for combinations to operate at concessional mass levels without prescribing specific loading methods or restricting commodity types

The Accredited Mass Management Scheme (AMMS) allows for approved tandem drive and tri drive combinations to operate at three concessional mass levels and does not prescribe specific loading methods or restrict commodity types. Instead, AMMS allows for any product and any proven loading control method to be used.

 To be eligible for AMMS, operators must be accredited under the WA Heavy Vehicle Accreditation (WAHVA) Mass Management Module.

AMMS period permits are available for a duration of 6, 12 or 36 months.

Cost: Refer to the AMMS Period Permit Fee Schedule

AMMS Approved Weighbridges

When addressing the criteria for the relevant standard in the WAHVA Mass Management Module, an approved weighbridge can be used by transport operators as their sole loading control method.

For a weighbridge to be included on the AMMS Approved Weighbridge List it must be able to determine and record both:

  • the gross mass of the vehicle; and
  • individual axle group weights.

The weighbridge operator must also provide current certification or calibration documentation with their AMMS Weighbridge Application Form.

An approved AMMS weighbridge will also be subject to an occasional audit to ensure ongoing compliance with the requirements.
